8.1i PACE/Floorplanner - A DCM instantiated in Synplify v7.7.1 targeting a Virtex-4 cannot be dragged and dropped


Keywords: DCM_ADV, Synplicity, Spartan, 6.3

A DCM instantiated in Synplify v.7.7.1 targeting a Virtex-4 cannot be dragged and dropped in PACE or Floorplanner v6.3. Consequently, I cannot constrain the DCM placement with these tools. If the DCM placement is constrained by the UCF file, it does not appear in PACE and Floorplanner. However, the tools place the DCM where it was constrained in the UCF file.

This also happens when changing the target device from a Virtex or Spartan family to a Virtex-4 family.


To work around this issue, instantiate a DCM_ADV in Synplify and include the library "virtex4.v" or "virtex4.vhd."
